Answer:

17242,5J

Explanation:

Given parameters:

Mass of water = 75g

Initial temperature = 20°C

Final temperature = 75°C

Unknown:

Amount of heat absorbed = ?

Solution

To find the amount of heat absorbed by water;

H = mcΔt

m is the mass

c is the specific heat capacity of water = 4.18J/g°C

Insert the parameters and solve;

H = 75 x 4.18 x (75 - 20)

H = 17242,5J

A laboratory analysis of a 100 g sample finds it is composed of 1.8 g hydrogen, 56.1 g sulfur, and 42.1 g oxygen. What is its em

Neporo4naja [7]

Answer: The empirical formula is $H_2S_2O_3$

Explanation:

If percentage are given then we are taking total mass is 100 grams.

So, the mass of each element is equal to the percentage given.

Mas of H = 1.8 g

Mass of S = 56.1 g

Mass of O = 42.1 g

Step 1 : convert given masses into moles.

Moles of H = $\frac{\text{ given mass of H}}{\text{ molar mass of H}}= \frac{1.8g}{1g/mole}=1.8moles$

Mass of S = $\frac{\text{ given mass of S}}{\text{ molar mass of S}}= \frac{56.1g}{32g/mole}=1.8moles$

Moles of O= $\frac{\text{ given mass of O}}{\text{ molar mass of O}}= \frac{42.1g}{16g/mole}=2.6moles$

Step 2 : For the mole ratio, divide each value of moles by the smallest number of moles calculated.

For H = $\frac{1.8}{1.8}=1$

For S = $\frac{1.8}{1.8}=1$

For O = $\frac{2.6}{1.8}=1.5$

Converting to whole number ratios

The ratio of H: S: O= 2: 2: 3

Hence the empirical formula is $H_2S_2O_3$

A ball has 2 kg* m/s of momentum when thrown with a velocity of 8 m/s outwards. Find the mass of the ball.

Advocard [28]

Answer:

$\large \boxed{\text{0.25 kg}}$

Explanation:

We can use the formula for momentum to calculate the mass.

$\begin{array}{rcl}p & = & mv\\2 & = & m \times 8\\m & = & \dfrac{2}{8}\\\\& = & \textbf{0.25 kg}\\\end{array}\\\text{The mass of the ball is $\large \boxed{\textbf{0.25 kg}}$}$

aalyn [17]

Answer:

gases are compressible and liquids arent

Explanation:

molecules of liquids have a very little space between them...but gas molecules have a larger space between them...so we can easily compress them...when we compresse them enough...at right temperature...even whole atmosphere turn in to liquid....
